The TCP spec mandates this behaviour:

  When a TCP socket is open when the serving process goes down,
  the port must not be reused until the TCP packet lifetime
  Motivation: if this would not be the case, then a new
    serving process could receive messages that have been
    sent to its predecessor. It would really been confused.

  If you know, what you are doing, you can disable this
  feature. There are socket options for this.
  I think, they are named "SO_REUSEADDR" and "SO_NOLINGER".
  See the socketoption documentation for details.
